Frequency: 226Hz. <strong>AT235</strong>h also: 678Hz, 800Hz, 1000Hz for traditional IYI-curve tympanometry.<br />
Level: 85 db SPL. Gain Control: AGC.<br />
Control: Automatic. Range: Default +200 to –400daPa (max. +300 to -600daPa).<br />
Safety limitation: -800 daPa <strong>and</strong> +600 daPa.<br />
Pressure change rate: Selectable in the set-up between 50, 150 <strong>and</strong> >250 daPa/s or automatic.<br />
Compliance: Range: 0.1 to 6.0 ml (numerical: 0.1 to 8.0 ml).<br />
Automatic, where pump speed, start <strong>and</strong> stop pressure can be userprogrammed in the set-up.<br />
<strong>AT235</strong>h: Auto <strong>and</strong> manual pump functions.<br />
<strong>AT235</strong>: Function test for use when the eardrum is intact.<br />
<strong>AT235</strong>h: Function tests for use with both intact <strong>and</strong> perforated eardrums.<br />
Atomatic reflex: Two independent user selectable protocols. Series of fixed intensities available.<br />
Automated intensity search functions available for threshold search <strong>and</strong> reflex growth indication.<br />
Free mixing of Ipsi <strong>and</strong> Contra.<br />
Manual reflex: Manual control of all stimuli. May also be used to redo part of automated test results.<br />
Reflex decay: Manual control, with stimulus duration of 10 sec. Ipsi or contralateral stimulation.<br />
Ipsilateral: Intensitiy up to 110dBHL. Frequency: 250, 500, 1000, 2000, 3000, 4000, WB, HP, LP noise<br />
Contralateral: Intensity up to 120dBHL. Frequency: 125 to 8000Hz, WB, LP, HP noise<br />
Audiometry: Intensity from -10 to 120dBHL. Frequency from 125Hz to 8000Hz<br />
1dB or 5dB steps.<br />
Internal memory for two ears. Each ear: 6 Ipsi <strong>and</strong> 6 Contra recordings. Each may have up to 6 stimuli.<br />
Also, there is memory for additional manual reflex recordings. (Total max. 78 reflexes per ear).<br />
Manual Audiometry.<br />
Automatic Audiometry according to ISO 8253-1 (Patient controlled Hughson-Westlake).<br />
Input/output for computer communication via USB. One mode allows an external PC to both monitor<br />
<strong>and</strong> control the instrument. The control actions can be followed on the display <strong>and</strong> operation panel.<br />
Online communication, where the measurement data are sent to an external PC can be selected.<br />
